GROOVE-ROLL MACHINE FOR REDUCING CEREALS FOR FOOD.

SPECIFICATION forming part of Letters Patent No. 532,698, dated J anuary15, 1 895.

Application filed March 31, 1394..

To all whom, it may concern:

Be it known that I, HENRY D. PERKY, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have'invented a certain new and useful Improvement in Groove-RollMachines for Reducing Cereals for Food; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification. 7

Figure 1, of the drawings is an end view of a machine embodying myinvention, partof the supporting .frame being broken away. Fig. 2 is avertical section of the same. Fig.

The. invention relates to groove roll machines for reducing grain orother articles of food to shredded or thread-like'form, and consistsmainly in the novel construction, and combination with the grooved rolland its discharging .comb, of acleaner for said comb, as hereinafter setforth. In these machines, although the grooved roll and the dischargingcomb, are of fine construction, theteeth and lands of the comb fittingneatly'the grooves and surface intervals of the roll, it is found thatparticles of the food material will, to some extent, pass thedischarging comb and accumulate on its upper marginal surface near theroll; and the object of this invenand saving this accumulation.

v In the accompanying drawings, the letter A designates a portion of theframe of the machine, carrying a pair of reducing rolls, whereof thefront roll B is formed with a series of fine circumferential grooves,the back The material fed between these rolls is compressed into thefine grooves of the roll B, and is discharged from these grooves inshred or thread-like form by the comb D, the teeth Serial No. 505,949.(No modem of which fit neatly into said grooves. This comb is secured tobearings of the frame, as indicated at E. v

F represents a small shaft, located below the reducing'rolls, and havinga pinion G, engaging the gear-wheel H of the grooved reducing roll. Ateach end this shaft is provided with a cam I, having a circular contourbroken by the notch J.

K indicates the combcleaner, which is usually a plate of steel extendingalong the top of the comb, but having an oblique position with referenceto the top plane of the comb, its lower or working edge a, when saidcleaner is moved inward being just clear of the top of said comb andfree of the surface of the grooved roll. This cleaner is designed tohave anintermittent quick movement in the direction of this roll, and togive it such motion, the lateral slides b,-are employed, these beingattached to the ends of the cleaner plate, and working in side bearingsc, of the frame in a reciprocating manner, intermittently, their motionbeing governed by the notch cams I. Springs (1, serve to hold the endsof the slides b, in engagement with said cams. At each revolution of thecams I, the cleaner is moved, as the slides enter and leave the notchesJ, suddenly toward the roll surface, and away therefrom a shortdistance, this distance being maintained by the engagement of thecircular portion e, of the. cams with the ends of said slides, until therotation of the cams brings their notches again to bear on the slides.This intermittent reciprocating cleaner, at each revolution of the cams,

quickly pushes whatever particles of mate-'- rial may have accumulatedon the inner edge of the comb toward and into the grooves of thereducing roll, so that they are taken up thereby and carried around insaid grooves to be mixed with the new material fed from the hopper, andutilized.
